    Hi Red,
    I have had a chat with a couple of sound/acoustic design engineers and the consensus was that the sonar analyses would be virtually impossible and implausible.
    First of all sonar works best when sound waves are bounced of a hard surfaces like metal, glass or wood.
    Soft tissue such as human skin(chest) is not a good surface to be working with.
    Then there is the really hard stuff to get around, soft cloth, as in pyjamas would serve to thwart this reflection process. This would put it in the nigh on impossible department, and then you throw in a sheet and possibly a blanket and the whole idea becomes mission impossible. Oh and one more thing, the directional nature of this procedure, how do you keep the subject from moving around.(lying on their back, on there other side, or putting their arm or hand in projection path.)
    In short, not going to happen.

    Regards,
    Phil.
